Definitions

  • the invention relates to a winding machine for winding a thread into a package according to the preamble of claim 1.
  • the winding machine is known from DE-OS 17 10 068.
  • a winding machine which also consists of two traversing devices.
  • motion laws for the first and second traversing device are specified, essentially with the content that the stroke lengths are essentially the same and that the first traversing device is operated with temporary acceleration before or after the stroke reversal with only a slight change in speed , while the groove profile of the grooved roller in the stroke reversal causes a sudden change in speed.
  • These laws of motion also apply to the traversing device according to the generic term.
  • the motion law according to the invention can also be used and results in exact thread guidance.
  • the first traversing device - in the yarn path - is developed in such a way that the guide ruler, which is arranged upstream or downstream of the driver arms, and the driver arms are assigned to one another and shaped in such a way that the driver arms give the thread an upper stroke.
  • the guide stroke of the first traversing device is greater than that of the coils 13nge in substantially corresponding traversing stroke of the subsequent second traversing device designed as a grooved roller.
  • the guide and driver arms are designed in accordance with the invention in such a way that the thread receives a very high acceleration in the opposite direction at the end of the guide stroke, so that it reverses its direction of movement and is moved back so far towards the center of the traversing stroke with extremely high acceleration and speed until it reaches the entry point into the Groove with approximately the routing angle.
  • the thread is then guided in the central region of the guide stroke essentially at the traversing speed of the grooved roller.
  • the first traversing device at the stroke reversing points with a slight change in speed and before and / or after the stroke reversing points is temporarily guided at a greater speed than the speed maintained in the central region of the traversing stroke and the stroke length of the first traversing device is approximately equal to the stroke length between the thread guide grooves
  • the first traversing device reverses the thread at the reversal points with a very high, theoretically with "infinitely” large change in speed in its direction of movement and with theoretically “infinitely” high speed in Can lead back to the center of the traversing stroke and thus ensures an exact guidance of the thread in the grooves of the grooved roller.
  • the required law of motion of the first traversing device can be achieved by designing the guide ruler upstream or downstream of the driver arms and the driver arms at their thread-guiding ends (cf. for example DE-PS 15 60 469).
  • This shaping is preferably carried out in the stroke reversal areas so that the thread also coincides with the middle area of the traversing stroke, the speed is guided up to the end of the guiding stroke and then reversed in its direction of movement with very great acceleration, and is again traced back to the movement law observed in the middle traversing stroke range to such an extent that it leads to the entry point of the groove at approximately the laying angle.
  • driver arms and guide ruler are designed so that the positive guidance of the thread is briefly released when the end of the guide stroke is reached, so that the thread snaps back under its own thread tension into the through the grooves of the grooved roller given motion law of the middle stroke range.
  • This upper stroke (0) is essentially equal to the drag length (L) x tangent alpha, where alpha is the laying angle of the thread on the bobbin, i.e. is the angle between the tangent lying in the normal plane and the thread.
  • Fig. 1 shows the cross section
  • Fig. 2 shows the view of an embodiment of the winding machine according to the invention, partially schematically.
  • the thread 3 running continuously in the direction of 2 is first guided through the stationary thread guide 1 and then through the traverse 4.
  • the winding spindle 5 is freely rotatable.
  • An empty tube 10 is slipped onto the winding spindle 5.
  • the thread 3, which starts at a constant speed, e.g. freshly spun and / or drawn man-made fibers are wound on the empty tube 10 to form a cheese 6.
  • the empty tube 10 and then the forming coil 6 are driven at their circumference by a drive roller 21 (not visible in FIG. 2) at a constant circumferential speed.
  • the thread 3 is moved back and forth along the cross-wound bobbin by the traversing 4, which is described below.
  • the traverse 4 and the drive roller 21 are mounted together on a carriage 22 which is movable up and down on guide rods 24, so that the drive roller 21 can evade the growing coil diameter of the coil 6.
  • the weight of the slide 22 is partially compensated for by the support device 23 - here a cylinder-piston unit.
  • the support device can be controlled such that the carriage with the drive roller 21 lifts off the coil circumference.
  • the traversing 4 consists, on the one hand, of a wing traversing and, on the other hand, of a grooved roller 11 arranged downstream of this in the thread path.
  • the traversing has its own drive, not shown.
  • Wing traversing and grooved roller are connected in a geared manner (not shown).
  • the particular advantage of the traversing shown is that the depositing angle of the thread on the spool can vary - within limits - from the angle of inclination of the slots, since the traversing speed can be set independently of the spooling speed.
  • the wing traversing has the rotor 12 and the rotor 13. Both rotors can be mounted concentrically or eccentrically to one another. Both rotors are driven in opposite directions by a drive and gear, not shown, in gear housing 20.
  • the rotor 12 carries two or three or four driver arms 8 which rotate in the plane of rotation I (arrow 18).
  • the rotor 13 carries the same number of driver arms 7 which rotate in the closely adjacent plane of rotation II (arrow 17).
  • the driver arms guide the thread along the guide ruler 9. Each driver arm 8 transports the thread - in FIG. 2 - to the right and transfers it there at the guide end to a driver arm 7, which transports the thread in the opposite direction to the other guide end, where in turn one of the driver arms 8 takes over the return.
  • the grooved roller 11 has a grooved train. It should be mentioned that the groove depth changes in the course of the grooves.
  • the grooves preferably form an uninterrupted groove train. However, it can also be provided that the grooves run out on the surface in the central region of the groove roller.
  • the grooved roller is driven synchronously with the wing traversing in the illustrated case with a transmission ratio 1:20.
  • the law of motion with which the thread 3 is deposited on the bobbin 6 is essentially predetermined by the course of the groove train.
  • the thread is - as I said - given by the geometry of the ends of the driver arms and the guide 9.
  • the law of motion is determined on the one hand by the constant peripheral speed of the driver arms.
  • the thread also executes radial movements with respect to the driver arms, which are predetermined by the shape of the guide ruler.
  • the thread can be caused to move at an angular speed which is less or greater than the angular speed of the driver arms.
  • the curves 25 to 33 are path-time diagrams of the thread movement, the common abscissa being the traversing stroke H of the grooved roller or the guiding stroke F of the first traversing device, and each of the two curves being a separate time Has ordinates which are shifted relative to one another in such a way that a stroke difference of approximately the amount U results between two thread points considered at the same time in the first and second traversing devices.
  • the curve (groove course) 25 shows the geometry of a thread guide groove of the grooved roller at the right stroke end of the traversing stroke H.
  • the theoretical stroke end lies at point 26, which essentially also denotes the bobbin length.
  • the groove is slightly extended beyond this theoretical stroke in the branch 27 in order to take into account the fact that the thread deposited on the bobbin tends to slide inwards.
  • Curve 30 shows a part of the law of movement of the back and forth, which is given to the thread by the driver arms 7, 8. It follows from this that the guide stroke F of the first traversing device is greater than that Traversing stroke H. This difference is also called the carry-over of the thread and is denoted by U. The difference is on the one hand proportional to the distance L, which exists between the guide ruler 9 or the planes of rotation I, II of the wing and the surface line of the grooved roller 11, in which the thread runs on the grooved roller, and on the other hand proportional to the deposit angle alpha. The distance L, also called the drag length, is practically measured from the center plane between the rotation planes I and II.
  • the angle alpha between the groove between the groove of the grooved roller and the tangent to the grooved roller is referred to here.
  • the thread is first guided at a speed (branch 31) to the end of the guide stroke F, which essentially corresponds to the traversing speed of the thread deposit according to branch 28 of the curve 25 of the grooved roller, but with a forward run substantially corresponding to the distance U.
  • the thread is braked with an extremely high speed change and reversed in its direction of movement, so that it returns with excessive speed in the curve branch 32 into an area 33 which essentially with the curve branch 29 of the grooved roller, ie with the possibility a small deviation angle is aligned.
  • the course of the stroke 33 of the first traversing device in the middle stroke range corresponds to a path-time diagram, in turn, of the thread deposit 29 after the reversal of the stroke with a phase-like phase shift, so that at the same times the first traversing device is essentially ahead of the distance U of the second traversing device.
  • the strong deceleration and acceleration of the thread at the end of the guide stroke is achieved either by positive guidance or by releasing the thread. Suitable measures are shown in FIGS. 4 and 5.
  • the thread at the ends of the guide stroke F between the guide rule 9.1 and the curved guide rule 9.2, which in the 4 - are arranged one above the other, deflected.
  • the guide rails overlap. This overlap ends in an end region E.
  • FIG 5 shows a top view of the end pieces of the driver arms 7 and 8 and the guide rulers 9.1 and 9.2 in the end region of the guide stroke F of the first traversing device. Shown is a point in time that is shortly after the point in time at which the front tip of the driving arm 8 leaving the lifting area is immersed under the guide line 9.1 and has released the thread. At this earlier point in time the thrust edge 34 of the driving arm 7 entering the traversing stroke had not yet emerged from the guide ruler 9.1. With that, the end of the traversing movement came outward for the thread. The thread thus had no guiding motion at the end of the guide stroke. The thread was therefore able to spring back under the thread tension.
